The invention relates to a pressurized hydraulic rotation damper intended for use on a multiwheeled vehicle. The rotation damper comprises an outer housing and a lid that together enclose a damping-medium-filled main chamber, which chamber is pressurized by a pressure tank and divided by a delimiting blade/arm into two volumes. The damping medium flows between the two volumes in a duct delimited by at least a first valve and a second valve. These valves throttle the flow between the volumes when the blade moves in an inward and outward motion respectively, starting from an intermediate position where the two volumes are substantially equal in size, to an outer position, in which the blade bears against or is placed close to the inner face of the outer housing. The first valve controls the flow for outward motions and the second valve is used to control the flow for inward motions to either pass through the first valve, through the second valve or through both valves. |
